SPC Performance Toyota 4RUNNER & FJ UCA (PAIR)

Designed, engineered, tested, and assembled in Colorado, SPC Performance adjustable upper control arms are loaded with impressive features. They improve suspension travel, handling, and tire wear while centering the tire in the wheel well for maximum clearance needed for oversized tires. Now equipped with maintenance-free ball joints and free-pivoting xAxis™ sealed flex joints in bonded rubber sleeves, for correction of alignment angles and restoration of factory ride quality. A forged steel design provides the strength and durability needed for the most demanding environments. SPC adjustable control arms have improved clearance to get around the spring bucket and a full 80° of articulation in the ball joint. When trucks are lifted, caster and camber angles are affected that can lead to poor handling characteristics such as ‘wandering’. SPC control arms have positive caster built-in for lifted vehicles to restore alignment angles and driveability. The patented ball joint design allows the tire to be positioned correctly in the wheel well, and additional adjustment in the OE lower arms can maximize placement for oversized tires to avoid fender trimming. If replacement lower adjustment cams are needed, see part #25440 or #25435 depending on year. Sold as pairs. US Patent No. 7,513,514.

Arm's adjustment range combines with OE adjusters to correct alignment angles for improved drivability and reduced tire wear, and makes it possible to move the tire forward to maximize clearance for 33” tires without frame or fender modifications. Forged steel arm construction provides maximum strength & clearance with additional caster provision for lifted vehicles built-in. The new ball joint has 25% larger stud cross section than OE for superior strength & E-Nickel coating for superior corrosion protection while providing 80° of articulation & extended threads make these arms compatible with knuckle gusset kits. New fully sealed ball joint architecture keeps grease in and contaminants out for a maintenance-free joint. One piece polymer race Ball Joint with modern grease formula ensures quiet smooth operation & low turning torque for reduced wear and extended life that tests like OE. New xAxis™ sealed flex joints in bonded rubber bushings allow for extended suspension travel & superior noise vibration and harshness (NVH) characteristics. Sold as a pair. Front Adjustment Range: Camber ±2.00° / Caster 0.00° to +4.00°. Required: 1 per axle.

Installation typically involves basic hand tools and is a moderate difficulty DIY task. Ensure the vehicle is properly supported and alignment is checked after installation. Factory hardware may be reused. Pay close attention to torque specifications for all fasteners.

These control arms are specifically designed for lifted vehicles to correct alignment angles and provide clearance for oversized tires. They are not intended for stock height vehicles unless alignment correction is specifically required. Always verify compatibility with your specific vehicle modifications.
